Description

In mould, automatically cut off edge-gated mould
Technical field
The present invention relates to injection-moulding plastic, is in mould, automatically to cut off edge-gated mould.
Background technology
Edge-gated: it claims again side gate.It is cast gate to be opened in to the die joint of mould, from the charging of goods lateral edge.It can adjust gate size easily, controls shear rate and cast gate off-period, is that mould is manufactured a kind of gate form that boundary extensively adopts.Its cross sectional shape adopts rectangle, thermoplastic to inject more conventionally.Cast gate can, according to the features of shape of goods and mold filling needs, be selected the position of cast gate neatly.As shaped as frame or endless shaper article, cast gate can be located at goods outside.And when its endoporus has enough positions, gate location can be located to goods inner side, and can make like this mould features compact structure, flow process shortens, and improves condition of molding.It is applicable to a multi-cavity mold, can enhance productivity, but it is that goods and running gate system clout connect together with in aggregates to deviate from outside mould after die sinking, therefore cause at mould and remove cast gate inconvenience outward, labor strength is large, at mould, remove by hand the easy cut wound goods of cast gate main body outward, directly affect products appearance quality, simultaneously the size inaccuracy of product edges after manual excision cast gate.In order to overcome this difficult problem, I am combined in mould and manufacture line experience spy for many years and provide following a kind of mold mechanism to solve the problems referred to above.
Summary of the invention
The present invention is to provide the edge-gated mould of automatic cut-out in mould, due to edge-gated, in existing mold manufacture, be extensively employed, but exist mould to excise this weak point of cast gate outward, therefore in conjunction with existing mold and its weak point, spy solves its weak point with following a kind of mold mechanism.It is achieved in that after moulding by casting, when mould is opened, because injection nozzle (9) retreats, at this moment the sprue bush (8) that is arranged on cover half one side loses pressure, so sprue bush (8) is upspring under the effect of the first spring (6), therefore the plastics in sprue bush (8) deviate to be pulled to dynamic model one side, opening due to active and inactive mold again, at this moment the second spring (3) that is arranged on dynamic model one side loses pressure and upsprings, and upspringing of the second spring (3) promotes pushing block (4) goods and gate cutting.Automatically cut off edge-gated mould in mould, having solved the existing edge-gated mould that enters to water can not automatic break gate, must be when mould adopts manual excision cast gate outward labor strength large, products appearance poor quality's problem.Solved existing mold and must excise at mould that cast gate, production efficiency are low, the problem of waste of manpower outward.This mould automaticity is high; mould structure is simple; mould manufacture, installation, debugging, easy to maintenance, this mold mechanism is manufactured boundary to mould and can be brought great economic worth simultaneously, and it is applicable to plastic injection and metal crimp mold uses when adopting edge-gated charging.In mould, automatically cut off edge-gated mould, it is characterized in that: the first spring (6) is arranged on sprue bush (8), sprue bush (8) and solid plate (12) matched in clearance, pressing plate (11), solid plate (12), top clamping plate (16) is fastenedly connected, nozzle of injector (9) compresses cast gate (8) when matched moulds, nozzle of injector (9) separates with sprue bush (8) when die sinking, the first screw (2) is fastenedly connected with pushing block (4), the second spring (3) is arranged on the first screw (2), described the first screw (2), pushing block (4), the second spring (3) forms the edge-gated shut-off mechanism of mould, this model core (5) is arranged on dynamic mould fixing plate (15), core (5) while and the first moving platen (13), the second moving platen (14) matched in clearance, the second screw (18) is fastened on core (5) on dynamic model backing plate (16), the first moving platen (13), the second moving platen (14), dynamic mould fixing plate (15), dynamic model backing plate (16), Bottom clamp plate (17) is communicated with and fastening rear formation mould dynamic model part.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described
Shown in figure:
Fig. 1 is the sectional side elevation while automatically cutting off edge-gated mould matched moulds cast in mould
Fig. 2 is the sectional side elevation while automatically cutting off edge-gated mould die sinking cut-out cast gate in mould
In figure, numeral number represents respectively:
1---injector push rod 2---first screw 3---the second spring
4---push pedal 5---core 6---the second springs
7---the 3rd screw 8---sprue bush 9---nozzle of injectors
10---top clamping plate 11---pressing plate 12---solid plates

16---dynamic model backing plate 17---Bottom clamp plate 18---the second screws
The specific embodiment:
Be automatically to cut off edge-gated mould in mould as shown in the figure, this model's point is while utilizing injector folding mould, the compression of nozzle of injector (9) and sprue bush (8) and separated goods and edge-gated cut-out.Its operation principle is as follows: when mould is installed in injector, debugging completes, through moulding by casting, pressurize feeding, after cooling and shaping, mould dynamic model part is with moving after injector, now the clout of goods and running gate system is moved to dynamic model one side simultaneously, meanwhile nozzle of injector (9) retreats, due to retreating of nozzle of injector (9), therefore sprue bush (8) loses pressure, at this moment the first spring (6) is upspring and is forced sprue bush (8) to retreat, so far the sprue clout in sprue bush (8) is deviate from, injector is moved after continuing to drive dynamic model part, now sprue bush (8) separates completely with pushing block (4), therefore pushing block (4) loses pressure, because pushing block (4) has lost pressure, at this moment the second spring (3) is upspring, force pushing block (4) action, the runner part that pushing block (4) action forward promotes in running gate system is inferred goods and edge-gated contact position, so reach the object of mould automatic break gate.After running gate system is separated with goods, after partly continuing, moves injector driven mold dynamic model, when die sinking is apart from being greater than after goods height, injector stops rear mobile work, now injector push rod (1) promote the second moving platen (14) and the first moving platen (13) goods from core (5) outside launch mode.During matched moulds, contrary action when mould is done die sinking, respectively opens after the complete closure of part when mould, just carries out the moulding by casting in next cycle.
